Practically every country of Africa is prone to desertification, but the Sahelian countries at the southern fringe of the Sahara are particularly vulnerable.
What areas in Africa have desertification?
estimates about 30 million acres of land across the globe are impacted by desertification every year. The most vulnerable region is a 3,000-mile stretch of land that includes ten countries in the Sahel region of Africa. The Sahel is the area between the Saharan Desert and the Sudanian Savannah.
Where does desertification occur most?
Africa is the continent most affected by desertification, and one of the most obvious natural borders on the landmass is the southern edge of the Sahara desert. The countries that lie on the edge of the Sahara are among the poorest in the world, and they are subject to periodic droughts that devastate their peoples.
Which region of Africa is most at risk from desertification?
Desertification is the process of land turning into desert as the quality of the soil declines over time. Many countries around the world suffer from the problems caused by desertification but it is the Sahel region of Africa where the effects are greatest.
What continent does desertification not occur?
With the exception of Antarctica, desertification affects every continent. According to the UNEP (United Nations Environment Program), 36 million square miles of the world are currently affected by this.
Which African country is losing its rainforest most rapidly?
Ghana is losing its rainforest faster than any other country in the world. Published May 1, 2019 This article is more than 2 years old. Ghana’s rainforest is being lost at an alarming rate, according to a new report about the state of forests worldwide.
What are three effects of desertification in Africa?
Desertification affects topsoil, groundwater reserves, surface runoff, human, animal, and plant populations. Water scarcity in drylands limits the production of wood, crops, forage, and other services that ecosystems provide to our community.
What are 3 causes of desertification?
Human activities that contribute to desertification include the expansion and intensive use of agricultural lands, poor irrigation practices, deforestation, and overgrazing. These unsustainable land uses place enormous pressure on the land by altering its soil chemistry and hydrology.
How many countries are affected by desertification?
Severe land degradation is now affecting 168 countries across the world, according to new research released by the United Nations Convention to Combat Desertification (UNCCD).
How can desertification affect humans?
Land degradation and desertification can affect human health through complex pathways. As land is degraded and deserts expand in some places, food production is reduced, water sources dry up and populations are pressured to move to more hospitable areas. … the spread of infectious diseases as populations migrate.
What is Africa doing to stop desertification?
Preventive actions include: Integrating land and water management to protect soils from erosion, salinization, and other forms of degradation. Protecting the vegetative cover, which can be a major instrument for soil conservation against wind and water erosion.
Why is Africa at risk of desertification?
Fire is a primary cause of desertification in the Sahel region of North Africa, where the degradation of drylands is especially pronounced. The degradation of drylands in Africa is forcing people who can no longer make a living off the land to move to urban areas.
What is the main cause of desertification in Africa?
Poverty-related agricultural practices are a major contributor to desertification. Continuous cultivation without adding supplements, overgrazing, lack of soil and water conservation structures, and indiscriminate bushfires aggravate the process of desertification.
What is the main cause of desertification?
‘Climatic variations’ and ‘Human activities’ can be regarded as the two main causes of desertification. removal of the natural vegetation cover（by taking too much fuel wood）, agricultural activities in the vulnerable ecosystems of arid and semi-arid areas, which are thus strained beyond their capacity.
Where is Desertification a problem?
Africa is the worst affected continent; with two-thirds of its land either desert or drylands. Almost a third of land in the U.S. is affected by desertification; and one quarter of Latin America and the Caribbean, and one fifth of Spain. * Desertification is mainly a problem of sustainable development.
At what rate is desertification happening?
More than 75 percent of Earth’s land area is already degraded, according to the European Commission’s World Atlas of Desertification, and more than 90 percent could become degraded by 2050.
